⚠️ This forecast assumes your current interest rate stays the same for your entire remaining loan term. In reality, your rate will likely change — fixed-rate periods in Australia/NZ typically run 1-5 years before reverting to a variable rate, and variable rates can change at any time. Use this as a guide to see the impact of extra repayments, not as a guaranteed payoff date.
🔁 What if you refinanced?
This is "the math if" — you enter a rate to explore, and we do the arithmetic. It's not a search for real available rates or lenders (that's what the AI tool below will do).

Want to know what refinance deals are actually available to you?
The math above is free — and it always will be. What it can't do is tell you which lenders will actually approve you, at what real rate, today. Our upcoming Refinance Advisor AI will search current rates and lenders matching your situation and hand you a shortlist, so you don't have to spend an afternoon comparing five bank websites yourself.
